Now that I see that a Haswell refresh of the 11s is out (at least at Best Buy) - I am wondering if you have any thoughts on these two. My primary concerns would be that I do like my Civ 5 - and am unsure whether the slightly downgraded specs on the 11s (core i5 4210Y vs core i5 4200U cpus - Intel 4200 vs. 4400 graphics) would be likely to make a notable difference in how the game plays.

To my mind, the primary advantages of the 11s would be a) the smaller size feels more appropriate for the tablet/laptop conversions (and I have been using an 11" laptop for a while now, so am already used to small screen, and somewhat cramped keyboard) b) price. c) the hope that, since it is driving a smaller screen, and slightly lower power components - the 11S is more easily portable (either they put less weight into the battery - or you get somewhat longer battery life)

I might have circumstances where I would appreciate the much higher resolution of the Yoga 2 Pro display, but I doubt they come up often enough to justify the price differential.

Do you have any additional information I should be considering here?

Any chance you will get a Haswell version of the 11s and do a smackdown between these two? I do appreciate your reviews, and would particularly like to see someone apply basically consistent tests of battery life and performance benchmarks to the two machines.

The Yoga 11s won't play Civ V as smoothly as the Yoga 2 Pro. The Y series CPU and Intel HD 4200 are indeed slower. And honestly, Civ V is pushing what Ultrabooks can do already. That doesn't mean you won't be able to run it, but computations between turns will take a while as the game progresses on the 11s. It's lower resolution at least won't tempt you to run the game at full HD .

Decided to pull the trigger on 11s. It seems to be playing Civ V acceptably for now (although, admittedly, I have not gotten to a real late game yet - so have not experienced much of the slow-down you warn about) - and am particularly appreciating a) an SSD - b) light weight and c) much better battery life (last laptop was an Alienware M11x - which made the screen really pretty - but was heavy, ate up battery life in a hurry whenever the discrete graphics was on, and was still using a spinning hard drive, so disc access/boot time/program start etc. were all much slower than the 11s).
